Residential Damper Ultra Low NOxGas Water HeaterThe FVIR Eco-Defender Safety System® Models Feature:■ ENERGY STAR® Qualified—Meets or exceeds requirements for ENERGY STAR® per the

latest ENERGY STAR® criteria revision, as well as most utility rebate programs.■ Bradford White ICON System™—Intelligent gas control with spark to pilot ignition system

eliminates the constant burning pilot. This results in savings of pilot gas during standby periods (120 VAC).-- Enhanced Performance—Proprietary algorithms provide enhanced First Hour Rating and

tighter temperature differential.-- Advanced Temperature Control System—Microprocessor constantly monitors and

controls burner operation to maintain consistent and accurate water temperature levels.-- Intelligent Diagnostics—An exclusive green LED light prompts the installer during start-

up and provides ten different diagnostic codes to assist in troubleshooting.-- Pilot On Indication—Flashing green LED provides positive indication that pilot is on.-- Separate Immersed Thermowell—High-strength advanced polymer composite

thermowell provides isolation between electric temperature sensor and surrounding water. No need to drain the tank when removing gas valve.

■ Automatic Flue Damper—Reduces standby heat loss, resulting in less gas consumption, higher energy factor ratings, and improved overall efficiency.-- Ten Foot Power Cord—Included (120 VAC).

■ Defender Combustion Chamber—Incorporates the Advanced ScreenLok® Technology Flame Arrestor and large split-door design to prevent ignition of flammable vapors outside the water heater.

■ Ultra Low NOx Burner with Primary and Secondary Air Distribution Devices—Ensures proper air to gas ratio for reduction of NOx generated by the combustion process.

■ Digital Thermal Sensor and Resettable Thermal Switch—Coordinates with self diagnostic control to prevent water heater operation when needed.

■ Maintenance-Free—No regular cleaning of air inlet openings or flame arrestor is required under normal conditions.

■ Sight Window—Offers a view into the combustion chamber to observe the operation of the pilot and burner.

■ Factory-Installed Hydrojet® Total Performance System—Sediment reducing device that also increases first hour rating of hot water while minimizing temperature build-up in tank.

■ Vitraglas™ Lining—An exclusively engineered enamel formula that provides superior tank protection from the highly corrosive effects of hot water. This formula (Vitraglas™) is fused to the steel surface by firing at a temperature of over 1600°F (871°C).

■ Insulation System—Non-CFC foam insulation covers the sides and top of tank, reducing the amount of heat loss. This results in less energy consumption, improved operation efficiencies, and jacket rigidity.

■ Pedestal Base—Rugged and durable base allows easy transport and positioning while providing corrosion-resistant contact with floor.

■ Water Connections—3⁄4" (19mm) NPT factory-installed true dielectric fittings extend water heater life and simplify water line connections.

■ Factory-Installed Heat Traps—Design incorporates a flexible disk that reduces heat loss in piping and eliminates the potential for noise generation.

■ Protective Magnesium Anode Rod—Provides added protection against corrosion for long-term, trouble-free service.

■ 3x4 “Snap Lock” Draft Diverter—Allows either 3" (76mm) or 4" (102mm) vent connections.■ T&P Relief Valve—Installed. ■ Low Restrictive Brass Drain Valve—Durable tamper proof design.■ Design Certified by CSA International (formerly AGA/CGA).■ Complies with the latest Ultra Low NOx requirement (10 ng/J NOx limit).
